VALVE.

Application filed March 28, 1921; Serial No. 456,163.

To all whom it'mag concern.

Be it known that we, JOHN W. PEARSON and J OSEPH S. POWER, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Valves, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to valves and in par-' ticular to valves on a drain.

We have shown our lnventlon cheaply and in large quantities, the elimination of any machine work wherepossible, is essential. It is also essential that the drain for the washing machine be located at a convenient point below the machine while the operation of the drain should be at the top of the machine so that the operator will not have to bend over to get the water out of the tub. One of the great objections to the modern power washing machine is the difhculty of draining it. In many washing machines it is customary to have an internal hump or division in the bottom of the tub over which the water and clothes are drawn. This adds additional difficulties to draining the tub as there must be two outlets from the tub proper communicating with, preferably, a single exit.

It is also the object of our invention to provide a drain which will not necessitate a projecting spout to convey away the waste water as this spout would interfere with the operation of the mechanism to which the drain is attached and in which the valve is installed.

Referring to the drawings:

Fig. 1, is a diagrammatic view of a washing machine tub, drain and valve installed in combination. 1

Fig. 2, is a section of the valve and the bottom of the tub to which it is attached with the control wire broken in order to in clude the entire operating mechanism within the scope of the drawing.

Referring to the drawing, 1 is the bottom adapted to I a drain on a washing machine, one of its. thereby permit 'ating wire 10.

' of a washing machine tub, 2 is that portionof the tub which rises abruptly as a hump 1,463,093: sari-tar; caries.

in the bottom of the tub, 3 is the bottom proper of the tub in which there is a grating 1- to prevent the clothes from falling into the opening and area occupied by the valve itself. 5 is a drain casing which communicates at one end with a drain pipe 6. This drain pipe 6 isnot essential but in some types of washing machines is installed so that it will communicate with the other side of the tub on the other side of-the hump 2 and of draining of both'sides of the tub.

7 is an openingin this drain casingl5 through .which the water enters the drain casing-from the tub 1., In normal operation the area 8 within the casing 5, as well as the area within the tube 6, is filled with water and oneof the problems to be solved is to-so construct the operating means for necessary. 1 This is accomplished in the presentinstance bythe use of a Bowden wire control consisting of a ca'sing9 and anoper- This wire and casing are conveyed upwardly to the top of the tub where a suitable support 11 will maintain it in position. An operating head 12 is mounted on the end of the wire. point of exit of the wire lO is above the general level of the water,'no special packing is necessary.

The casing 9 is rigidly secured in the tube 6 at 13 and projects downwardlyand lat- As the erally, terminating in a head 14. This head 14 serves as a guide for the plug 15 which slides upon it. The plug 15 is actuated, by the wire 10 which isfastened to it between the nuts 16 and 17. This member 15 is a pearshaped body having a metallic casing on its head at 18. A rubber gasket 19 is placed inthe orifice 20 of the casing 5. The pear-shaped member 15 and its casing 18 engage with this rubber gasket 19 thus making a tight fit. The Bowden wire control holds the member 15 in close engagement with 19. This eliminates all necessity for machine work. A simple casting 15 is suiiicient; the rubber 19 makes aclose connection and a water tight arrangement to prevent the exit ofvanyfluid from the tub. A downwardly projecting fin 21 is provided on 19 so that the water will drip into a receptacle'without splashing on the floor.

This part 21 is so arranged that it will not.

interfere with the normal reciprocation of the tub in the washing machine.

Whilewe have shown and described certain features as constituting our invention, it will be understood-that parts have been shown for purposes of illustration'only, and;

that We do not desire to be limited to such details, as obvious modifications will occur to a person skilled in the art. v

Having thus fully described our inven- 'tion, what we claim as new and desire to secure by Letters Patent, 1S

1. In a valve a casino an exit 0 enin a resilient seat therein, a valve member adapted to engage with said seat, means for actuating said valve member into and out of engagement with said seat, and a drain lip on said resilient seat on the exterior of said casing.

2. In a valve, a casing, an exit opening,

a resilient seat therein, a valve member adapted to engage with said seat, means for actuating said valve member into and out of engagement with said seat, a drain lip on said resilient seat on the exterior of said casing, and means of introducing liquid into said casing. v p

3. In combination, a casing an entrance opening in said casing, an exit opening therefrom,'; an annular resilient member in said exit opening forminga seat therein, said member having a portion to engage the casing and another portion removed there- 'from exteriorof the casing for draining the liquid away from the casing and the valve mouth, a valve member adapted to.

seat in: said opening, a Bowden wire control for directing and actuating said valve member, operating means for actuating said Bowden wire above the level of the liq an aperture through said valve seat, anda semicircular lip con'nected to saidfvalve seat but spaced therefrom to drain surplus fluids away from said valve seat.

5. In combination, a casing consisting of a chamber, an exit opening and entrance opening, a pear shaped valve member, a bolt and wire centrally located therein, a bolt and wire casing, and means toactuate said "wire and said valve member, a resilient valve seat in the exit opening having one portion thereof adapted to yieldingly engage the walls of the exit opening, and a semicircular portion removed therefrom on the exterior thereof but connected therewith,

located on the lower half thereof, adaptedv to drain away fluidsand' passing there-. through in such a wayasto not allow the fluids to run back into the valve or to run along the exterior of the casing.

' Intestimony whereof, we aflix our signatures.
